CI/CD Sandbox: DNS resolution not working.

Hi team,

 

Link to the Sandbox:

https://devnetsandbox.cisco.com/RM/Diagram/Index/be51af73-c9e9-4af7-89d2-42c1c71e1f09?diagramType=Topology

 

I logged into the devbox: 10.10.20.50

  • SSH access to the DevBox 10.10.20.50 server using credentials developer/cisco123

[developer@devbox ~]$ ping google.com
ping: google.com: Temporary failure in name resolution

 

[developer@devbox ~]$ git clone https://github.com/CiscoDevNet/cicd_learninglab_demo.git
Cloning into 'cicd_learninglab_demo'...
fatal: unable to access 'https://github.com/CiscoDevNet/cicd_learninglab_demo.git/': Could not resolve host: github.com; Unknown error

[developer@devbox ~]$ cat /etc/resolv.conf

I got it at the end.

Seems like the sandbox all have the local hosting for the end-to-end solution and does not need to use GitHub.

Just because I am following this lab:https://developer.cisco.com/learning/lab/cicd-intro/step/2

 

Hello @vantruongsinh this is correct - sandboxes have limited (some none) internet access due to the security posture. Did you find in the learning lab instructions requiring external connection?

 

Thanks!

Hi @bigevilbeard ,

In the lab note https://developer.cisco.com/learning/lab/cicd-intro/step/2, it did mention that I will need to clone the repository.

A. Our sample codebase
SSH to the devbox, clone the git repository

ssh root@10.10.20.20
# password is cisco123
git clone https://github.com/CiscoDevNet/cicd_learninglab_demo.git
cd cicd_learninglab_demo

 

 

There is another guide in the sandbox note, which makes more sense.

https://devnetsandbox.cisco.com/sandbox-instructions/CICD_Pipeline/helloworld.html

 

Regards,

Sinh
